| description | A thin wall liner is positioned within the circular bowl of a sand muller to overlay the interior mulling surface upon which foundry sand is placed and is mulled by a plow blade that rotates within the bowl over its mulling surface. The bowl surface is annular and ring-like in shape. The liner is formed of a number of similar segments which are arranged together in edge to edge relationship to form an annular, ring-like cover over the bowl surface. The liner segments are secured to the bowl by bolts which extend through aligned holes in the segments and in the bowl. Most of the outer surface of the liner is spaced a short distance from the bowl surface by means of thin pads formed on the outer surface of the liner, around the area of the bolt holes. The pads contact the bowl surface, to provide a space between the remainder of the liner and the bowl surface. This space is filled with a grout-like material for bonding the liner to the bowl and for shock absorbing and load distribution. The liner is formed of a hard material which is much more wear resistant than the bowl to permit extended use of a worn bowl or to extend the life of an unworn bowl. |
